Re: [ECOS] arm-elf & ecos

[Andrew Lunn <andrew dot lunn at ascom dot ch>]

Like i said earlier, its to do with the line endings and the way you
have mounted the filesystems.

ANSI standard says that nothing should follow the \ continuation
character except the line feed. If you have M$ line endings, there is
a carriage return before the line feed. cygwin can mount its drives in
either binary or text mode. In text mode, it inserts carriage returns
before line feeds to keep M$ applications happy. In binary mode it
does not. You need to ensure your sources are on a binary mount point
and you do not corrupt your sources by using a editor which inserts
carriage returns.
